Abstract

Ocean acidification (OA) is the decline in seawater pH and saturation levels of calcium carbonate (CaCO3) minerals that has led to concerns for calcifying organisms such as corals, oysters and mussels because of the adverse effects of OA on their biomineralisation, shells and skeletons. A range of cellular biology, geochemistry and materials science approaches have been used to explore biomineralisation. These techniques have revealed that responses to seawater acidification can be highly variable among species, yet the underlying mechanisms remain largely unresolved. To assess the impacts of global OA, researchers will need to apply a range of tools developed across disciplines, many of which are emerging and have not yet been used in this context. This review outlines techniques that could be applied to study OA-induced alterations in the mechanisms of biomineralisation and their ultimate effects on shells and skeletons. We illustrate how to characterise, quantify and monitor the process of biomineralisation in the context of global climate change and OA. We highlight the basic principles, as well as the advantages and disadvantages, of established, emerging and future techniques for OA researchers. A combination of these techniques will enable a holistic approach and better understanding of the potential impact of OA on biomineralisation and its consequences for marine calcifiers and associated ecosystems.

Abstract

Unterricht wurde lange ausschließlich als Diskurs untersucht, aber jeder Unterricht erfordert auch einen fachbezogenen und didaktischen Umgang mit materiellen Dingen. In dem neuen ZISU-Band fragen die AutorInnen aus der Perspektive erziehungswissenschaftlicher und fachdidaktischer Unterrichtsforschung, wie Dinge im Unterricht genutzt werden, wie sie zu Dingen des Unterrichts werden und sich im Unterricht verändern und welche Bedeutung Dingen bei der Konstituierung von Lernsituationen zukommt.; For a long time, teaching has been examined exclusively as discourse, but all teaching also requires a subject-related and didactic approach to material things. In the new volume of the journal "ZISU", the authors ask from the perspective of educational science and didactic teaching research how things are used in class, how they become material matters of class and how they change in class, and what significance things have for the constitution of learning situations.

Abstract

L’apparition des moulins dans le paysage s’est faite très tôt avec, sous l’Ancien Régime, une période d’activité dense et riche où le meunier a un rôle social très en vue dans le monde rural. À partir du xviiie siècle, les progrès techniques améliorent la productivité des moulins. Puis sous l’impulsion de la Révolution industrielle, l’introduction de la vapeur et/ou des turbines permet de moins dépendre du régime saisonnier des rivières. Le cœur des moulins : Archives départementales de la Gironde est issu d’une exposition présentée par les Archives départementales de la Gironde de novembre 2015 à mars 2016. Les contributions d’universitaires et d’érudits invitent à pénétrer au cœur d’une économie rurale et de réseaux de sociabilité développés autour de la mouture des céréales, de la vente des farines et des autres productions des moulins.

Abstract

L'histoire du livre technique constitue un champ neuf et peu développé. Si elle est relativement moins connue que celle du livre de science ou de la littérature artistique, elle concerne pourtant une production extrêmement riche, qui représente et met à l'œuvre l'intelligence pratique et l'esprit d'invention. Il suffit de penser aux Descriptions des arts et métiers, commandées au plus haut sommet de l'État sous l'Ancien Régime, aux spectaculaires « théâtres de machines », aux manuels de fonctionnaires circulant dans tout l'empire chinois, aux multiples traités qui ont formé des générations d'ingénieurs ou encore aux guides techniques destinés à améliorer les pratiques des artisans et des agriculteurs, pour comprendre qu'il s'agit d'une littérature importante à caractère universel faisant l'objet de circulations intenses entre les différentes parties du globe. L'objet de ce livre est à la fois de combler une lacune du champ historique et d'interroger les relations entre l'économie du livre et le monde de la technique afin d'analyser la catégorie du livre technique à travers ses formes, ses fonctions, ses modes de diffusion et d'appropriation, avant le xxe siècle. Cet ouvrage contribue ainsi au dynamisme de l'histoire des techniques, soucieuse d'affirmer sa dimension culturelle, comme une histoire des savoirs et des représentations, et de s'inscrire dans les débats de l'histoire globale.

Abstract

Micro-extraction techniques in sample preparation are gaining interest among analytical chemists as they comply with green analytical chemistry demands and ensure environmental protection and public safety. Savings in cost and time are considered as valuable benefits by using novel micro-extraction approaches in sample handling. Selectivity, sensitivity and lower detection limits are also included among the performance characteristics required to meet the legislation criteria.The target of this special issue is to present the state of art in microextraction sample preparation techniques. Modern, simple and efficient methods for preconcentration and separation are described for different analytes isolated from various matrices.

Abstract

Chaque époque invente une nouvelle façon d’écrire l’histoire ou, du moins, cherche à éclairer le présent en interrogeant différemment le passé. Depuis une trentaine d’années, les données produites par l’archéologie, notamment par les fouilles préventives, ont cru de façon exponentielle, ouvrant ainsi de nouvelles perspectives de recherche sur l’histoire des techniques et de l’économie antiques. Face à l’indigence des sources écrites, l’archéologie livre aujourd’hui des séries de documents per...

Abstract

Bacteria are always present in foods, either as initial contamination or as technological agents. In solid foods, they are immobilized and develop as colonies. So far, there is a lack of knowledge about the bacteria in colonies, growth and physiology. Non-destructive and resolute techniques, such as fluorescent microscopy, now allow investigating the world of bacteria in colonies and their surroundings in food, at the microscopic scale.
